Groton Homeowner’s Guide to Selecting an Oil Company
For Groton homes heating with number two heating oil, selecting which of the 34 heating oil companies that serve Groton makes a big difference.
Full Service Oil Companies: Homeowners who value a “set-it-and-forget-it” heating system choose one of the 19 “full-service” oil companies that serve Groton. Full service companies such as Spicer Advanced Gas or Midknight Oil offer households annual contracts which consist of a combined package of both automatic number two heating oil delivery and heating system repair.

The family does not need to monitor the level of the oil tank or place individual orders.
Discount Oil Companies: also referred to as “COD Fuel” or “Cash Heating Oil” companies, discount oil companies are for customers who are on a budget. With discount oil companies, in return for better prices, you monitor the heating oil level in your tank, and you place an oil order when the oil gauge dips below a quarter tank.
